I made a nice little tool I like to call SkillSelect. It lets you save builds to a file and recall them at any point, which is pretty basic. The cool part is that if you're running Diablo III you can have the tool auto-set your build for you so you can switch between two entirely different builds very easily.

(it's all just AutoIt and doesn't hook the game or anything stupid like that. Just mouseclicks.)
Right now I only have coords for 1920x1080 but it's pretty trivial to make settings for different resolutions. Give it a shot.
